RE: [Crsupportgroup] Tanita Scales/% Body FatRMR

[Guest guest]

I had considered modifying mine so instead just measuring between the two foot

pads one electrode was connected to both feet, and a

second electrode connected to both hands... this would probably need to be

re-calibrated but it might be a little more stable.

They seem to measure one electrical characteristic and weight, are told age,

sex, and general activity level, then use a look up

table or simple formula. This approach is hugely variable since the measurement

varies so much with hydration level, bladder

contents, etc.

They would do themselves a great service if they simply built in an averaging

function so they could average over multiple readings

and not appear so variable.

Otherwise it's a pretty good weight scale and a nice toy.

Subject: [Crsupportgroup] Tanita Scales/% Body FatRMR

In a recent discussion on % BF, several have mentioned (me included)

that they like to use one of the scales made by Tanita. While they

have limitations, they do show trends.

In a recent move, I damaged mine, and was about to get a new one, when I

noticed that they just came out with a new line that is supposed to not

only measure %BF, but also Body Water %, Muscle Mass, Bone Mass, Basal

Metabolic Rate, Metabolic Age, Visceral Fat and Physique Rating.

I am not sure how they are doing it, or their accuracy and have

contacted them about it, but I have also ordered the top ironman model

to try it out. I am interested mostly in the RMR and Bone Mass.

So, if anyone else is interested, you can see the new scales here.

Rodney, maybe you want to also look into how they are proposing to do

this.

PS again, no financial interest in the company at all

PSS, just about finished with 100 MedGem RMR tests and will compare them

to standard RMR equations, like HB and see how they do.

There are professional models of this techolofy that do attach the electrodes at

the hands and feet and send the sginal through the whole body, but these are

usually around several $1000s of dollars
